TECHNICAL FIELD

The technical field relates generally to power management and morespecifically to distributing power in network communications equipment.

BACKGROUND

It is important for network services providers to protect theirequipment from power failures. Without protection, if a power failurewere to occur, then portions, or even the entirety, of a network couldfail cause service disruptions for the users of the network. The type ofprotection may vary depending on the location of the equipment. Forinstance, a centrally located server farm may have one type ofprotection whereas user equipment, located within a user's premises, mayhave another type of protection. Often, a network service provider willprovide back up for central locations while relying on users to back upthe equipment located within their respective dwellings.

In certain network environments, such as fiber fed or copper accessenvironments, there is often edge equipment that services multipledwellings within a single unit. For example, an apartment building mayhave a distribution point unit (DPU) placed within a control area of amulti-dwelling unit. To protect the DPU from a power outage a backuppower source would have to be co-located and maintained within or nearthe DPU. Providing power back-up in this manner is not optimum fornetwork service providers or the owners and operators of multi-dwellingunits because the network service providers must maintain the backupequipment, and the owners must provide space for the backup equipment.

To overcome these difficulties, the present disclosure presents amethods and systems for intelligent power distribution.

DETAILED DESCRIPTION

Referring to FIG. 1 , a system 100 is shown that includes a distributionframe (DF) 102 and one more instances of a user unit 113(1) . . .113(n). DF 102 in one example is a device or facility at which opticalcables are terminated, interconnected, and/or distributed. For example,DF 102 may be a main distribution frame (MDF) or intermediatedistribution frame (IDF) of a network communication system.

It should be noted that system 100 is shown in an exemplaryconfiguration for illustrative purposes in this disclosure and shouldnot be limited to what is depicted in FIG. 1 . System 100 may includeadditional DFs 102 and user units 113(1) . . . 113(n). System 100 mayinclude addition user equipment and/or network equipment beyond thatwhich is shown. In addition, the configuration of system 100 may takeother forms. For instance, there may be a plurality of DFs 102 ornetwork equipment located within system 100 and between DF 102 and userunits 113(1) . . . 113(n). In addition, user units 113(1) . . . 113(n)may include additional equipment and/or different configurations thanwhat is shown in FIG. 1 . Referring further to FIG. 1 , DF 102 in oneexample includes a power source 104, a multiswitch 106, a distributionpoint unit (DPU) 108, an intelligent power distribution (IPD) component109, and one or more ports 110.

Power source 104 provides the electricity that powers DF 102. Powersource 104 in one embodiment may be a power interface to a publicelectrical grid. In another example, power source 104 may be a powerinterface to a private electrical grid. In another example, power source104 may be a power interface to a power source, such as a generator orbattery bank.

Multiswitch 106 in one example is a device that distributes a signal tomultiple end points. In the example shown, multiswitch 106 receives asatellite signal and distributes the signal through outputs 107(1) . . .107(n) through ports 110 to user units 113(1) . . . 113(n). It should benoted that the depiction of a satellite signal is used for illustrativepurposes only and other types of data signals are contemplated by thisdisclosure. In addition, multiswitch 106 may be operable to receivemultiple input signals and distribute signals to multiple end points.

DPU 108 in one embodiment is a device that receives signals from a fiberoptic network, processes the signals, and then distributes the processedsignals to user units 113(1) . . . 113(n). In one example, DPU 108connects to a fiber optic network and then modulates signals that itreceives for distribution over existing wiring, such as copper telephonewiring or coaxial cable, of user units 113(1) . . . (113(n).International Telecommunication Union (ITU) standards ITU-T G.9700 andG.9701, which are hereby incorporated by reference, describe examples offunctionality by which fiber optic signals may be processed anddistributed over existing wiring. DPU 108 includes outputs 111(1) . . .111(n) which correspond to user units 113(1) . . . 113(n). DPU 108 mayreceive power from power source 104. DPU may also receive power fromuser units 113(1) . . . 113(n) in accordance with principles ofoperation that will be further described herein.

Ports 110 receive outputs 107(1) . . . 107(n) from multiswitch 106 andoutputs 111(1) . . . 111(n) from DPU 108, combine the signals, anddistribute the combined signals over interfaces 112(1) . . . 112(n) touser units 113(1) . . . 113(n). In one example, a port 110 may be acombiner or demultiplexer.

Referring further to FIG. 1 , DPU 108 in one embodiment includes IPDcomponent 109. It should also be noted that although IPD component 109is shown as part of DPU 108, it also may be a standalone component, orit may reside in another part of a network in which system 100 resides.IPD component 109 provides functionality which determines a power modeof DPU 108. In one embodiment, the power mode describes the sources ofpower that are used to power DPU 108. For example, in a first powermode, DPU 108 may receive power exclusively from power source 104. In asecond power mode, DPU 108 may receive power exclusively from user units113(1) . . . 113(n). In a third power mode, DPU 108 may receive powerfrom a combination of power source 104 and one or more of user units113(1) . . . 113(n). In a fourth power mode, DPU 108 may receive powerfrom one or more user units 113(1) . . . 113(n) if a condition shouldoccur, such as a loss of power at power source 104.

It should be noted that a power mode may also include providing abalance among a number of power sources and/or components or devices tobe powered. For instance, if DPU 108 were powered by user units 113(1) .. . 113(n), IPD 109 may determine the percentage of power that each userunit 113(1) . . . 113(n) is providing to DPU 108. The percentages may bethe same for the user units 113(1) . . . 113(n) or the percentages maybe unique to the user units 113(1) . . . 113(n). IPD 109 may alsodetermine percentages between power supply 104 and user units 113(1) . .. 113(n). For example, IPD 109 may determine that power supply 104should provide 50% of power to DPU 108 and user units 113(1) . . .113(n) should provide the other 50%. Then, IPD 109 may determine that afirst user unit 113(1) should provide a certain percentage of the 50%and the other user units 113(n) should provide the remaining percentageof the 50%. IPD 109 may also determine that certain components of DPU108 will be powered by user units 113(1) . . . 113(n) and certaincomponents will not. In another example, IPD 109 may determine thatcertain components of DPU 108 will be powered equally by user units113(1) . . . 113(n) and other components of DPU will be powered entirelyby the user unit 113(1) . . . 113(n) that uses such components.

Referring further to FIG. 1 , user units 113(1) . . . 113(n) in oneexample are locations, facilities, or dwellings at which an entityconsumes data that is provided to the user units 113(1) . . . 113(n)from the DF 102. For example, a user unit 113 may be an apartment, ahouse, an office, or any location in which network data is received byan entity. User units 113(1) . . . 113(n) in one example comprise powersourcing equipment (PSE) 114, user equipment 116, power source 118, andport 120. In addition, one or more (or none) of user units 113(1) . . .113(n) (e.g., user unit 113(1)) may include a power backup system 122.The preceding components are coupled together through connectors 124,such as wiring or cable. The letter “n” represents the number of userunits 113 to which DF 102 provides service. For example, DF 102 wouldprovide service to 4 user units if n were to equal 4 or 8 units if nwere to equal 8. This disclosure does not contemplate a theoreticallimitation on the value of n.

PSE 114 in one example provides the functionality by which power may besupplied by user units 113(1) . . . 113(n) to power one or morecomponents of DF 102, including DPU 108. PSE 114 is coupled to powersource 118 within user units 113(1) . . . 113(n). PSE 114 in one examplereceives power from power source 118 and injects the power into wiring124 such that power may be sent back to DPU 108 and used to power DPU108 and/or one or more other devices residing at DF 102. In anotherexample, shown with respect to user unit 113(n), PSE 114 injects powerinto wiring 124 through user equipment 116, which may have circuitry andfunctionality that allows the user equipment 116 to receive and sendpower. The preceding functionality is referred to as reverse powerfeeding. A description of reverse power feeding may be found in EuropeanTelecommunications Standards Institute (ETSI) standard 101 548 RPF andBroadband Form standard BBF WT-338, which are hereby incorporated byreference.

Due to reverse power feeding, it is possible for power provided by oneor more of user units 113(1) . . . 113(n) to power DPU 108 and/or one ormore other devices at DF 102. As was discussed earlier, DPU 108 may beentirely powered by power source 104 or by user units 113(1) . . .113(n) through reverse power feeding. In another example, DPU 108 may bepowered by a combination of power source 104 and reverse power feeding.In another example, DPU 108 may be powered by power source 104 unless acondition occurs making it desirable to power DPU 108 by reverse powerfeeding. For instance, if a loss of power were to occur at DF 102, DPU108 may elect to draw power from user units 113(1) . . . 113(n) throughreverse power feeding.

Referring further to FIG. 1 , user equipment 116 may include variousdevices that reside within user units 113(1) . . . 113(n) and areutilized to receive and/or consume data. For example, user equipment 116may include, but is not limited to, video receivers, network terminationequipment (NTE), cable modems, routers, personal computers, laptops,laptops, tablets, etc.

Power source 118 provides the electricity to user units 113(1) . . .113(n). Power source 118 in one embodiment may be a power interface to apublic electrical grid. In another example, power source 118 may be apower interface to a private electrical grid. In another example, powersource 118 may be a power interface to a power source, such as agenerator or battery bank.

Port 120 is operable to receive combined signals from ports 110 of DF102 and distribute the signals to the various user equipment 113 withinthe user units 113(1) . . . 113(n). In one embodiment, port 120 isoperable to split signals from DF 102 and distribute the signals overwiring 124 to user equipment 113. In one example, port 120 may be atriplexer.

Power backup system 122 in embodiment is a battery backup system. Inanother embodiment, power backup system 122 may be a generator. Powerbackup system 122 is operable to provide power to user unit 113(1) inthe event that user unit 113(1) loses power. For instance, user unit113(1) may lose power and accordingly, power source 118 may not be ableto provide power to user equipment. Therefore, power backup system 122could be actuated, either automatically or manually, such that it couldprovide power to user equipment 116. In one embodiment, power backupsystem 122 would also provide power to power sourcing equipment 114, aswill be discussed further herein. It should be noted that user unit113(1) is shown with power backup system 122 and user unit 113(n) isshown without such a system for illustrative purposes only. It should beunderstood that some, all, or none of user units 113(1) . . . 113(n) mayhave power backup systems 122.

In addition, it should be understood that the description providedherein should not be construed as being limited to the exemplaryconfiguration of system 100. The principles of intelligent powerdistribution as described herein may be applied to other systems toprovide power backup intelligently and selectively from a first system,having a backup power system, to one or more components of a secondsystem, which does not have a backup power system, but that is providinga service to the first system.

Referring to FIG. 2 , an exemplary description of DPU 108 will now beprovided for illustrative purposes. DPU 108 in one example comprisemanagement and control layer 202, optical uplink 206, aggregator 208,silicon intelligence 210, analog front end 212, one or more instances ofline driver 214, DC Block 216, Power conversion component 224, and IPD109.

Management and control layer 202 in one example provides the centralmanagement and control functionality to operate DPU 108. For instance,management and control layer 202 may control the input, output, anddistribution of signals to/from DPU 108.

Optical uplink 206 is the interface that connects to the primary fiberpoint. In one embodiment, optical uplink 206 is a small form factorpluggable (SFP) transceiver. In another embodiment, optical uplink 206may include multiple SFP transceivers. For instance, one SFP transceivermay connect to the primary fiber point and another SFP may be used toconnect to another DPU 108 in the event that an operator wanted to daisychain DPUs 108. Optical uplink 206 may be operable to connect to one ormore fiber optical networks, such as a passive optical network (PON), agigabit passive optical network (G-PON), and a XG-PON network.

Aggregator 208, silicon intelligence 210, and analog front end 212 arethe components that receive and process bi-directional data signalsreceived through optical uplink 206 or from user units 113(1) . . .113(n). These components process, modulate, demodulate, combine, and/orseparate signals for transmission over the primary fiber network or touser units 113(1) . . . 113(n). For example, aggregator 208 mayaggregate traffic and host management software. Silicon intelligence 210in one example comprises a field programmable gate array (FGPA)comprised of a plurality of digital signal processors that drive signalto a corresponding user unit 113(1) . . . 113(n). Analog front end 212in one example is utilized to modulate digital signals into analogformat such that they may be transmitted over an analog domain.

Referring further to FIG. 2 , line drivers 214(1) . . . 218(n) in oneexample are bi-directional amplifiers corresponding to outputs 111(1) .. . 111(n) that amplify signals to/from analog front end 212 such thatthey have sufficient signal strength to reach their respective user unit113(1) . . . 113(n). DC block 216 is utilized to extract DC voltage fromthat is sent from user units 113(1) . . . 113(n) over interfaces 112(1). . . 112(n) in accordance with reverse power feed technology. DC block216 in one example provides extracted DC voltage to IPD 109 overinterface 217.

Power conversion component 224 receives power from power source 104 andconverts AC power to DC power for utilization by DPU 108.

Referring further to FIG. 2 , an exemplary description of the operationof IPD 109 will now be provided for illustrative purposes.

As was discussed earlier, in one embodiment, IPD 109 determines thepower mode of DPU. In one example, IPD 109 may make a power modedetermination for DPU 108 and provide instructions to management andcontrol layer 202 to implement the power mode. In another embodiment,IPD 109 may include the functionality to implement the power modeitself. Implementing the power mode may take different forms. In oneexample, IPD 109 may receive power, from power conversion component 224and DC block 216, and distribute the power to one or more components ofDPU 108 or DF 102 to power those components in accordance with the powermode that it has calculated.

For example, IPD 109 may elect to receive power from one or more of userunits 113(1) . . . 113(n) and no power from power source 104, or viceversa. In another example, IPD may elect to receive power from one ormore user units 113(1) . . . 113(n) and from power source 104. IPD 109may elect to power all or some of the components of DPU 108 inaccordance with power mode it selects. For instance, if there were apower outage in user units 113(1) . . . 113(n), IPD 109 may select apower mode by which it only receives power from those user units 113(1). . . 113(n) that include power backup systems 122. IPD 109 may elect topower only those components of DPU 108 that provide service to the userunits 113(1) . . . 113(n) with power backup systems 122. IPD 109 in oneexample may power components of DPU 108 such that the user units equallyshare the burden 113(1) . . . 113(n) having power backup systems 122.

Referring to FIGS. 2 and 3 , an exemplary process 300 of intelligentpower distribution will now be described for illustrative purposes.

In step 302, IPD 109 monitors power distribution and activity of DPU 108in accordance with a power mode. In one example, IPD 109 may providepower to all of the components of DPU (i.e., optical link 206,aggregator 208, line drivers 214, etc.) through power drawn entirelyfrom power source 104. In step 304, IPD 109 may detect a change in thepower consumption of system 100. For example, IPD 109 may detect a poweroutage at power source 104. If a power outage were to occur, IPD 109 maycontinue to function through use of power reverse power provided by oneor more of user units 113(1) . . . 113(n). In another example, IPD 109may utilize a source of backup power to continue to function.

Referring further to FIG. 3 , in step 306, IPD 109 senses utilization ofthe components of DPU 108 from user units 113(1) . . . 113(n). It ispossible that there may be a power outage in one or more of user units113(1) . . . 113(n). If that were the case, then those user units 113(1). . . 113(n) with power backup systems 122 would continue to havefunctioning user equipment 116. Those user units 113(1) . . . 113(n)would also be the only units capable of providing reverse power to DPU108. IPD 109 would sense which user units were continuing to function.IPD 109 may sense such activity by monitoring signals being sent overinterfaces 112(1) . . . 112(n). In another example, IPD 109 may have arecord of the user units 113(1) . . . 113(n) that have power backupsystems 122. For instance, an entity may register that its user unit 113has a power backup system 122 prior to a power outage taking place. Insuch an example, IPD 109 may have access to a database of user units113(1) . . . 113(n) that have power backup systems 122.

In step 308, IPD 109 would determine a new power mode. In one example,determining a new power mode comprises using the number of user units113(1) . . . 113(n) that continue to function as a parameter incalculating the new power mode. In one example, IPD 109 may elect toonly power those components of DPU 108 serving user units 113(1) . . .113(n) that continue to function. In a power outage, if user unit 113(1)and 113(2) were the only user units that continued to send/receive datafrom DPU 108, IPD 109 may determine to power only those components ofDPU 108 that provide service to units 113(1) and 113(2). Some or all ofthe components of DPU 108 that serve the other user units 113(3) . . .113(n) would not receive power. For example, IPD 109 may elect to onlysupply power to LD 214(1), LD 214(2) and those portions of aggregator208, silicon intelligence 210, and analog front end 212 that serve userunits 113(1), 113(2). IPD 109 would not provide power to the othercomponents and subcomponents.

In step 310, IPD 109 would implement the power mode determined in step308 and return to step 302 in which it would monitor the powerconsumption and activity in DPU 108. If power were to return to theother user units, IPD 109 would sense activity from interfaces 112(3) .. . 112(n) and resume powering those portions of DPU 108 that serve userunits 113(3) . . . 113(n).
